Title: Proximity switch for lights - detects movement using Doppler effect and takes time of day and background illumination into account
Inventor: HERBORG KARLHEINZ
IPC: H03K17/945
Filed: 1978-10-26
Abstract: The proximity switch consists of a combination of a conventional timing circuit and a circuit for measuring background illumination. An ultrasonic signal (or similar) is transmitted and reflected from objects in the vicinity of the switch. A comparator compares the transmitted (S) with the reflected (E) received signal and initiates the timing circuit, which in turn initiates the drive circuit that controls the light. A circuit to suppress certain kinds of movement is located between the comparator (U) and the timing circuit (T). A circuit that disables the proximity switch at certain times and/or at certain background levels of illumination is located between the timing circuit and the drive circuit.

Title: Childproof medicine package - with inner bead weakened at marked section for easy depression
Inventor: ZANKER HELMUT
IPC: A61J1/14
Filed: 1979-07-24
Abstract: The parent patent described a package for medicine which is made childproof by a tightly fitting stopper which can be lifted by an adult by depressing a marked thinner shell wall section. The same effect can be achieved if the internal bead on the shell is made eccentric or has a thinner local section which is again marked on the outside by a dot. Depression of this section gives a hold for the fingers under the top of the stopper to lever it out of the bead. This creates a very simple childproof closure.

Title: Gas pressure regulator - monitors output pressure to operate solenoid valve to input flow or vent to atmosphere
Inventor: ROBENS ERICH
IPC: B01J19/00
Filed: 1979-09-20
Abstract: A gas pressure regulator of the type used in gas analysis equipment is designed to maintain close tolerance operation. The system uses electromagnetic actuators to control the supply and exhaust of fluid to and from the reaction chamber of the analyser. The pressure in the reaction chamber (1) is measured by a pressure gauge (2) and is compared with the required reference value. If the measure pressure is too low, an electromagnetic actuator opens a valve (3) to allow fluid to be supplied from a charged bottle (8). Thermal switches are operated after a predetermined time. If the pressure in the reaction chamber is too high a valve (7) is opened to allow fluid to be vented to atmosphere. Other thermally controlled valves (5,6) operate after a specified interval.
